Gmail, Google's email service, has quite a few features to its name. One feature it lacks is the ability to do a "find and replace" with an email. If you receive an email and want to do some quick find and replace editing before you reply or forward the message, you can't--that is, unless you use a trick involving Gmail's "Create a document" feature. You can learn how to Find & Replace in Gmail by following a few steps.
Log into your Gmail account at Gmail.com.
Open the email you want to perform find and replace on by clicking on it inside your inbox.
Click the "More actions" button and, from the drop-down list, click "Create a document."
Open the "Edit" menu and click "Find and replace."
Type the keyword you want to find into the "Find" field, then type the word you want to replace it with into the "Replace with" field.
Click the "Replace all" button. All instances of the "Find" word you provided will be replaced.
